Abstract
The invention relates to a dowel for arranging in lightweight building boards, wherein a lightweight building board has a first cover layer and a second cover layer made of compact, pressure-resistant material and, arranged between the cover layers, a core layer made of material having a lower density than the cover layers, comprising a first dowel part and a second dowel part, wherein the first and the second dowel part are designed to be displaceable relative to one another, in which dowel the first dowel part and the second dowel part each have at least two fingers which extend parallel to a longitudinal direction of the dowel, wherein, in the plugged-together state of the first and second dowel part, the fingers of the first dowel part and the fingers of the second dowel part inter-engage at least in certain portions.
